Rename len() to size() for compatibility with openCypher

[sapalli2989]

Currently Kuzu uses len() to get the length of a list (and strings). openCypher names this function size(), which is also the standard in Neo4j.

So I guess the suggestion is to just rename function len -> size.

Hi @sapalli2989, this make sense to me. Will make the change soon.

That was fast :-). With the risk of repeating myself, but in this case I gladly do it: Much appreciated!

Hi,
Here is the URL to the list functions documentation: https://github.com/kuzudb/kuzu-docs/blob/main/docs/cypher/expressions/list-functions.md
Internally, we implement size() as an alias of len(), so you can simply add another function called size() which is an alias of len()
